Repeat previous effect
Repeats the closest effect “above” (the previous effect).
When being in a note column: Copies all effect columns from the previous line with at least one effect.
When being in an effect column: Copies only the previous effect in that column.
Keybinding preference is found under Global:Tools:Repeat Previous Effect
(I have it set to ctrl-r)
I hope it’s bug free. Let me know if you want it to handle vol/pan/dly columns in some way, or if you just like it
